Cook pasta according to package directions. Drain well and set aside. In a 10-inch pan, saute garlic in olive oil. Add spinach, broccoli, red pepper and grilled chicken; toss to combine. Stir in Alfredo sauce and pesto; simmer an additional 5 minutes. Reheat pasta if necessary under hot running water in a strainer; pour into a pasta bowl. Pour Alfredo sauce mixture over bow ties. Sprinkle with Italian seasoning and Parmesan.
